Dear Student,
As we know that power -energy relation:
As we know that power -energy relation:
Power = Energy /time
2kW=E/t
=>E=2x1000x60
=>E=12x104 J
mgx10=2000x60
=>m=1200kg
2kW=E/t
=>E=2x1000x60
=>E=12x104 J
mgx10=2000x60
=>m=1200kg
Cheers!!

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
